1. Clean out your res_mods folder, but if you do, any other mods you are running will be gone too.
2. Dokan Library as poster above mentioned
3. Re-download the XVM and figure out what files were added to res_mods and just delete those files. May impact other mods.
4. Just start the game using the normal short-cut rather than the XVM proxy short cut you set up when you installed XVM. The files will still be there, but you won't be connected to the XVM server for the data.

Personally, I would wait 24 hours until 8.6 comes out and it will take care of it for you.
